Definitions
- the present invention relates generally to the field of reclosable bags and more specifically to reclosable bags that use or incorporate tamper evident, hermetic seal, and reclosable fastener assemblies or mechanisms of the slider or zipper type.
- the present invention is particularly concerned with a reclosable bag that may be filled with a food product at a factory or food processing plant and then sealed to protect the food product until such time as a customer purchases the reclosable bag and opens it to access the food product within.
- Reclosable, typically flexible, containers are well known in the art. Such containers normally comprise a bag-like structure made from a folded web of material, like thermoplastic film. These types of containers may also include reclosable zipper structures, as well as interlocking male and female zipper elements fused, extruded, or attached to the bag sidewalls. Alternatively, the reclosable zipper structures, mechanisms, or assemblies may also be identified as slider closure systems, i.e., a closure system for slider bags and form, fill and seal technology that contain two tracks that can be interlocked and a separate part (a slider) that rides on the tracks and is used to open and/or close the tracks. The bag-like structure is created when the thermoplastic film is folded, sealed, and severed along its exposed edges.
- Reclosable bags are a great convenience to the consumer. This is especially true where the food product or material contained within the bag is of a type that may not all be consumed at once, for example, shredded cheese, sliced cheese, cheese, processed cheese, deli meats, snack foods, vegetables, fruits, sweets, etc.
- a problem with these types of bags is achieving a design in which the food product is hermetically sealed against oxygen, atmospheric intrusion or transmission, bacteria, molds, and/or other sources of contamination, while also providing features that help to disclose to the consumer evidence of tampering without substantially interfering with the ease of use of the bag.
- HFFS Horizontal Form Fill and Seal
- VFFS Vertical Form Fill and Seal
- HMW Horizontal Flow Wrapper
- Tamper evident packaging may also require the use of several pieces of film, which must then be connected to each other. This can make manufacturing of the reclosable bag more complicated.
- thermoform type machines like the one disclosed in U.S. Pat. No. 4,240,241 could also be used to practice the present invention disclosed herein, after appropriate modification as the disclosure herein will make apparent.
- the bag structures include sidewalls or fin portions that extend up past the sliding type zipper structure. This interferes with the consumer's access to the food, makes it difficult to see the zipper structure, and also makes it more difficult to easily operate the zipper mechanism. This is especially true if the person opening and closing the bag is disabled, has arthritis, or another aliment, which limits the manual dexterity of that person.
- the present invention is believed to address these and other objectives by the unique and simple structures and methods disclosed herein.
- the present invention may generally be described as a reclosable bag for filling with at least one food product.
- the reclosable bag includes at least one sheet of web material.
- the sheet of web material has at least two areas of structural weakness and at least one fold structure located between and defined by the two areas of structural weakness.
- the reclosable bag includes an opening located generally opposite the fold structure.
- the reclosable bag includes a sliding fastener structure having a skirt structure of web material extending therefrom and located within the fold structure.
- the skirt structure or skirt material may be either integral to the slider fastener structure or it may be coupled, e.g., sealed or adhered, to the slider fastener structure.
- the skirt structure includes a distal margin that is coupled to the sheet of web material at a location between the areas of structural weakness and the opening.
- the web material of the reclosable fastener structure extending past the areas of structural weakness so that the reclosable fastener structure is located within the fold structure.
- the reclosable bag is capable of being filled with at least one food product through the opening.
- the reclosable bag structure of the present invention may optionally include other features.
- the skirt may include an outside surface and an inside surface.
- the distal margin is located on the outside surface.
- the inside surface may include a predetermined area having a releasable adhesive material. This allows for the option of having a peelable seal, which may be used to aid in making the reclosable bag initially hermetic and may also add another reclosable/resealable feature to the bag.
- reclosable, resealable, and releasable in addition to their normal meaning, are used herein, interchangeably, to describe a closed or sealed opening that may be re-opened at a predetermined time to aid in providing access to at least a portion of the contents of the bag, and then closed or sealed to allow the remaining contents to be stored in the bag for later use and/or provide evidence of tampering.
- the web material of the reclosable bag is substantially comprised of a predetermined portion of a roll of a parent film material.
- the predetermined portion having predetermined dimensions from which a reclosable bag of predetermined dimensions may be constructed.
- the parent film material may be manufactured to a specification which determines the shape and location of the areas of structural weakness and which makes the areas of structural weakness an integral part of the parent film. Presently, it is believed to be commercially preferred to do so.
- the areas of structural weakness could be applied to the parent film at a predetermined step of the construction or manufacturing process of the resealable bag.
- the areas of structural weakness may extend intermittently, continuously, and linearly, nonlinearly, or in some other predetermined pattern across a predetermined dimension of the sheet of web material.
- the predetermined dimension where the area of structural weakness is located may be either the length or the width of the reclosable bag, which is usually rectangular in shape, depending on whether or not it is desired to use the long edge or side of the bag or the short edge or side of the bag with the slider closure system. Use of the long edge of the bag provides for a larger opening and thus enhances the ease of access to the food material or other materials contained within the reclosable bag.
- structural weakness is generally used to describe that area of the reclosable bag that is intentionally designed to be easily torn by the consumer to provide for evidence of tampering and to allow for easy exposure of the zipper mechanism or assembly. Nonetheless, it should be understood that use of the term structural weakness should include, without limiting its meaning, structures such as perforation, scores, microperforations, and multiple laminate materials which include a layer having an area of material or materials which are specifically designed to be easily torn. Accordingly, it should be understood that the areas of structural weakness are intentionally designed to create a predetermined tear path, which may or may not be hermetic.
- opening of the bag may be facilitated by the application of a tear strip (e.g., tear tape or tear string) along a predetermined surface or surfaces of the parent film.
- a tear strip e.g., tear tape or tear string
- the tear strip may or may not be used in combination with a predetermined area of structural weakness.
- the present invention may be described as a reclosable bag for filling with at least one food product and comprising at least one sheet of a web material.
- the sheet of web material includes a first area of structural weakness and a second area of structural weakness.
- the areas of structural weakness may be tear areas or areas having a propensity to tear in a predetermined direction.
- the sheet of web material including at least one fold structure, located between and defined by the first and second areas of structural weakness, and a fill opening.
- the sheet of web material further comprising a first panel coupled to the fold structure at the first area of structural weakness and a second panel coupled to the fold structure at the second area of structural weakness.
- a reclosable fastener structure including a male track structure and a female track structure.
- the male track structure including a first fin structure of web material extending therefrom and the female track structure including a second fin structure of web material extending therefrom.
- Each fin structure including a predetermined coupling portion.
- the coupling portion of the first fin structure being coupled to the first panel and the coupling portion of the second fin structure being coupled to the second panel.
- the reclosable fastener structure extending past the areas of structural weakness and into the fold structure. The areas of structural weakness being located below the reclosable fastener structure.
- the alternative reclosable bags are also capable of being filled with at least one food product through the fill opening, which is subsequently sealed.
- the present invention allows the fold structure to be easily removed from the reclosable bag. More importantly the present invention allows the consumer to substantially expose the reclosable fastener structure so that it is easily accessible and the consumer does not have to be impeded by bag sidewalls or bag fin portions that extend up past the zipper structure. Finally, the present invention accomplishes this using but not limited to substantially one piece of film material.
- the present invention may be described as a reclosable bag for filling with at least one food product.
- the reclosable bag may include at least one sheet of web material, at least one tear tape structure, at least one fold structure, and an opening located generally opposite the fold structure.
- a reclosable fastener structure including at least one integral skirt structure of skirt web material extending therefrom.
- the integral skirt structure including at least one distal margin. The distal margin being coupled to the web material at, at least one location between the tear tape structure and the opening.
- the reclosable fastener structure extending past the tear tape structure and into the fold structure.
- the reclosable bag capable of being filled with at least one food product.
- the reclosable bag for filling with at least one food product may also be described as a reclosable bag including at least one sheet of web material having at least one fold structure presenting at least two sidewall structures having inside surfaces, and an opening located generally opposite the fold structure.
- a reclosable fastener structure including an integral skirt structure comprising a web material extending therefrom and including opposed distal margin structures. The web material of the integral skirt structure being sealed to the inside surfaces of the sidewall structures at a plurality of predetermined sealing areas.
- the reclosable bag may also include a barrier web material extending between and coupled to the distal margin structures.
- the barrier web material of the alternative bag may alternatively extend between and be coupled to the sidewall structures.
- the barrier web material may also be coupled to predetermined sealing areas by at least one peelable seal.
- the barrier web material may include at least one area of structural weakness that extends through it along a direction generally parallel to the predetermined sealing areas.
- the reclosable bag for filling with at least one food product of the present invention may include at least one sheet of web material having at least one predetermined tear area, at least one fold structure, and an opening located generally opposite the fold structure.
- a reclosable fastener structure including at least one integral skirt structure of skirt web material extending therefrom.
- the integral skirt structure including at least one distal margin. The distal margin being coupled to the web material at, at least one location between the tear area and the opening.
- the reclosable fastener structure extending past the tear area and into the fold structure.
- the reclosable bag capable of being filled with at least one food product.
- This alternative reclosable bag structure may further include at least one piece of a header material located in a predetermined area of the fold structure.
- the header material may include at least one edge structure adjacent the tear area.
- the reclosable bag of this alternative structure may further include at least one tear tape structure coupled to the web material and adjacent to the tear area.
- the present invention may be described as a method of construction using known form-fill-and-seal machinery including but not limited to HFFS, VFFS, and HFW machines.
- the steps of the method of construction include 1. Folding the sheet of web material along a predetermined folding area located between the areas of structural weakness to form the fold structure. 2. Inserting the reclosable fastener into the fold structure. 3. Coupling the distal margin of the integral skirt structure to the web material. 4. Sealing the web material along at least two predetermined linear areas located generally perpendicular to the fold structure. 5. Filling the reclosable bag with at least one food product through an opening. 6. Sealing the opening. Please note that in an HFW application it is presently believed that the step four should occur last.
- the method may also include a step of inserting either a tear tape or a tear string at least prior to step four. Further, a header strip could also be introduced prior to step four.
- the web material may be slit along the fold line and the reclosable fastener assembly inserted and sealed to result in an exposed zipper structure assembly at one end of the bag.
- the reclosable bag is designed to have a gusset opposite the zipper opening then the fill opening may be sealed and the bag may be filled with product through the zipper opening.
- the process and structure of the present invention could include a reclosable fastener assembly having two skirts or flaps of web material.
- the first skirt could be coupled or sealed to the parent film prior to folding the parent film.
- the first skirt could be tack or partially sealed prior to folding and then subsequently a full seal applied in the HFFS, VFFS, or HFW machine.
- the second skirt or flap After folding the parent film the second skirt or flap would be sealed to the film sidewall located opposite the sidewall to which the first skirt is sealed or coupled. Construction of the bag could then be completed as disclosed herein.

- skirt(s) 16 remain intact so that the zipper assembly 20 is kept continuous for ease of handling. Once inserted the skirt(s) 16 of the zipper assembly 20 is bonded to the inside surface 10 a of the parent film 10 at seal location(s) 14 .
- Next sides 30 and 32 are sealed, along margin 10 c illustrated in FIGS. 5 or 7 , using a known mechanism such as a heat-sealing bar of a form fill and seal machine by advancing the folded film 10 to the heat sealing bar portion of the machine used; creating a seal 30 a across the length and width of margin 10 c .
- the resulting bag 100 is then filled with a predetermined foodstuff or other desired material through the opening 33 located, opposite the zipper assembly 20 , at bottom edge 34 shown in FIG. 5 or 7 . Then bottom edge 34 is subsequently sealed, forming seal 34 a.
- Tear off portion 11 is integral to the parent film 10 . Integral tear off portion 11 may be easily removed by tearing along the score lines 12 , leaving the zipper structure 20 a fully exposed and easily accessible for the use desired.
- the above noted process and mechanism may also be performed so that the zipper assembly 20 is located along one of the long sides 30 or 32 of the bag 100 rather than the short side of the rectangle, which is defined by the bag 100 .
- FIG. 5 a second embodiment of the present invention 1 is illustrated. As may be seen from FIG. 5 two bags 100 are shown prior to their being separated along seam 101 .
- This embodiment includes score lines 12 laid out in an alternative pattern that includes curve or arcuate section 13 and tear notch 24 .
- the parent film 10 is sealed at section 26 to either its opposing sides 35 and 36 or the structure of the zipper assembly 20 .
- the tear notch 24 provides a starting point for removing the fold structure 11 , which is located above the zipper assembly 20 .
- the fold structure 11 being defined by the location of the score lines 12 .
- the score lines 12 extending along curve 13 to a predetermined area below the zipper assembly 20 for substantially the is entire width of the reclosable bag 100 facilitating removal of the hood or fold structure 11 and exposure of the zipper structure 20 a .
- the embodiment of FIG. 5 further including a hermetic seal 40 .
- FIG. 8 a cross-sectional view of the embodiment of FIGS. 5 and 6 may be seen.
- the integral skirt 16 usually comprised of two strips on pieces of plastic film or a one-piece unit of continuous film, may be seen to have its outside surface 19 sealed hermetically to the inside surfaces 36 a and 35 a at respective hermetic seals 40 a and 40 .
- a peelable seal 50 is located at the bottom of the skirt 16 . Any standard commercially known resealable adhesive 51 may be used to make the peel seal 50 .
- the peel seal 50 may also be a hermetic seal 40 b.
- FIG. 9 an alternative to the embodiment of FIG. 8 is shown.
- the zipper skirt 16 is heat sealed to the side panels 36 and 35 respectively of the parent film 10 .
- the inside surfaces 17 of the zipper skirt 16 are peelable sealed to one another, using a known releasable adhesive 51 , to provide a releasable hermetic or gas tight seal 50 therebetween.
- a known releasable adhesive 51 to provide a releasable hermetic or gas tight seal 50 therebetween.
- the term's resealable adhesive or releasable adhesive as used herein should be construed interchangeably as well as given their common meaning.
- FIG. 10 another alternative embodiment of FIG. 8 is shown.
- the parent film 10 is sealed along a predetermined portion 42 of inside surface 35 a and 36 a .
- a known releasable adhesive 51 is used to form a peelable seal 50 between inside surfaces 35 a and 36 a at predetermined portion 42 .
- U.S. Pat. No. 4,944,409 contains an example of such an adhesive.
- CUREX brand grade 4482-0 supplied by Curwood of Oshkosh, Wis. is considered an acceptable adhesive for use with this embodiment of the present invention.
- the peelable seal 50 is comprised of a peel seal tape 53 having a permanent sealant like a metallocene catalyzed polyethylene located on one side and a releasable seal material like the aforesaid CUREX brand material on the other side (side 54 ).
- FIG. 11 and 12 One possible method for achieving the structure of FIG. 11 and 12 is the use of a form fill and seal machine system in which the peel seal tape 53 would be tacked onto a predetermined location of the parent film 10 prior to the plow 200 .
- FIGS. 31, 33 , and 34 See FIGS. 31, 33 , and 34 for a general illustration of the location of the plow 200 in relationship to the other components of a form fill and seal machine.
- heat sealer bar 208 it is presently believed preferable for heat sealer bar 208 to be enlarged sufficiently so that in addition to sealing the tear tape 120 is place it also seals the permanent seal side of the peal seal tape 53 in place at the same time.
- sealer bar 208 is believed preferable for these separate functions multiple bars could be used, each having a dedicated function or a combination of functions).
- the peelable sealant side 54 would be sealed to the parent film 10 by heat sealer bars 55 .
- Use of sealer bars 208 and 55 as disclosed herein allows independent temperatures and pressures to be used for each seal and it is believed that more consistent peel seals will result.
- the zipper skirt 16 may be sealed in place subsequent to the plow 200 by sealer bar 56 and the header seal 206 a may be made by sealer bar 57 as illustrated generally in FIGS. 34 and 36.
- the zipper skirt 16 includes an elongated section 16 a .
- End 21 of elongated section 16 a is positioned between the inside surfaces 36 a and 35 a of the side panels 36 and 35 of the parent film 10 .
- the elongated section 16 a is heat sealed to the parent film 10 on inside surface 35 a and peelable sealed using a known releasable adhesive 51 to inside surface 36 a to form peel seal 50 .
- FIG. 14 a third embodiment of the present invention is disclosed. Again, two bags 100 are shown prior to their being separated along seam 101 .
- the invention of the third embodiment is comprised of parent film 10 , which is used to form the bag 100 that is to be filled.
- the bag 100 includes a first side seal 30 , a second side seal 32 , and a fill opening 33 .
- Side panel 35 forms the front side of the bag 100 .
- the fill opening 33 after the bag 100 is formed and filled with a predetermined type of food material, is heat sealed to form bottom edge or seal 34 .
- the bag 100 further includes a fold structure 11 , header 15 , integral zipper skirt 16 , a zipper assembly 20 including a zipper structure 20 a , at least one hermetic seal 40 , an unsealed area 60 , and a section 62 where the zipper skirt 16 and the ends 23 of the zipper assembly 20 are heat sealed together (see sealed mass 23 b in FIG. 14) prior to their insertion between the front side 35 and the back side 36 of the film 10 .
- the formation of sealed mass 23 b may take place at sealer 216 , which is illustrated in FIG. 30 .
- the zipper skirts 16 may have a predetermined portion or portions that extend past seal 40 and which may be held together with a peel seal 50 . See for example, FIG. 15 .
- the hood structure 11 (which may be defined by the score lines 12 ) may be easily removed to expose zipper structure 20 a .
- the sealed mass 23 b provides for containment of product when the peelable seal 50 is opened.
- FIG. 15 a view from line 15 — 15 of FIG. 14 may be seen. This may be seen to be identical to the embodiment of FIG. 8, except as explained above with reference to FIG. 14 .
- the zipper skirt 16 is made of one piece of material. It is heat sealed to the inside surfaces 35 a and 36 a to form hermetic seals 40 and 40 a .
- the skirt 16 is provided with a structural weakness 45 which extends linearly and generally parallel to hermetic seals 40 and 40 a along the zipper skirt 16 .
- the structural weakness 45 is designed to fracture or tear relatively easily when the customer opens the bag 100 .
- the zipper skirt 16 includes a barrier film section 16 b .
- the barrier film 16 b is applied (preferably by heat sealing although other methods could be used, e.g., Adhesive coupling, ultrasonic or high frequency sealing technology) to the inside surface 16 d of the zipper skirt 16 .
- the zipper skirt 16 is heat sealed along a predetermined portion of its outside surface 16 e to parent film 10 to form a hermetic seal 40 .
- the barrier film section 16 b is releasably sealed to the inside surface 16 d to form at least one peel type seal 50 . Note that it is presently believed that section 16 b must have a surface 16 c that is resistant to heat sealing.
- barrier film section 16 b is heat sealed to a separate predetermined portion of the inside surfaces 35 a and 36 a of the parent film 10 .
- the barrier film 16 b is provided with a structural weakness at 45 which extends linearly and generally parallel to hermetic seals 40 .
- the structural weakness is designed to fracture or tear relatively easily when the customer opens the bag 100 .
- FIG. 17 could be provided with a structural weakness 45 as described with reference to FIG. 18 .
- peel seal 50 would be replaced with a permanent seal.
- header strip 206 located between the front side 35 and back side 36 of the parent film material 10 , of a predetermined size have sufficient width to extend down to, preferably just above, a tear line 132 (area of structural weakness).
- the header strip 206 terminates at edge(s) 131 .
- This tear line 132 has the predetermined propensity to tear in predetermined way.
- the extension of the header strip material 206 extends down so that it is adjacent to the tear line 132 . This facilitates tearing off the hood structure 11 from the bag 100 along the tear line 132 .
- the optional tear notch 134 facilitates initiation of the tear
- the tear line 132 (the oriented parent film 10 or film 10 with the propensity to tear) directs the tear
- the header material 206 which is bonded or sealed to the front side 35 and back side 36 of the parent film 10 , controls the tear so that the zipper structure 20 a is consistently clear of the parent film material 10 after the removal of the hood structure 11 .
- the header material 206 is made of an oriented polypropylene having at least one side with a heat sealable sealant then the parent film 10 would not need to be oriented or have the tear line 132 or propensity to tear.
- the header material 206 is made of an oriented polypropylene then the oriented polypropylene should have both its sides coated with a heat sealable sealant.
- a plurality of header strips 206 could be used instead of a single integral header strip 206 . In either case, the parent film 10 would not necessarily need to be oriented or have a tear line 132 or a propensity to tear.
- At least one but preferably two pieces of tear tape 120 located between the front side 35 and back side 36 of the parent film material 10 on film surfaces 35 a and 36 a , of a predetermined size are bonded or sealed to the parent film 10 of the hood structure 11 adjacent, preferably just above, a tear line 132 (area of structural weakness).
- This tear line 132 has the predetermined propensity to tear in predetermined way.
- the tear tape material 120 adjacent the tear line 132 facilitates tearing off the hood structure 11 from the bag 100 along the tear line 132 in a controlled manner.
- the optional tear notch 134 facilitates initiation of the tear
- the tear line 132 (the oriented parent film or film with the propensity to tear) directs the tear
- the tear tape 120 which is bonded or sealed to the front side 35 and back side 36 of the parent film 10 , controls the tear so that the zipper structure 20 a is consistently clear of the parent film material 10 after the removal of the hood structure 11 .
- the tear tape material 120 is made of an oriented polypropylene having at least one side with a heat sealable sealant then the parent film 10 would not necessarily need to be oriented or have the tear line 132 or propensity to tear.
- the parent film 10 may be weakened in predetermined areas using other procedures as well, including but not limited to scoring or the use of multi-ply laminate film having a predetermined weakened area or the addition of a tear assistance structure, e.g., Tear tape 120 or tear string 120 a .
- the tear assistance structure may be added for use by itself or in conjunction with a predetermined area of structural weakness 12 to aid in the tearing of the film 10 . See FIGS. 28 and 29.
- tear tape 120 is applied to both the inside surfaces 36 a and 35 a and the outside surfaces 36 and 35 of the bag 100 .
- no score line or weakening 132 is believed necessary (although such an area of structural weakness could be used) since the tear tape 120 located on both the inside and outside surfaces of the bag 100 will act as an effective tear guide.
- FIGS. 24, 25 , and 26 another alternative to the embodiment shown in FIG. 22 is illustrated.
- a modified tear tape 120 b having a tear bead 120 c is used.
- FIGS. 24-26 illustrate, when the film 10 is sealed to the tear tape 120 b the bead 120 c is depressed into the film 10 creating an area of structural weakness 12 without requiring prescoring or other modification of the parent film 10 prior to the application of the tear tape 120 b .
- This structure is believed beneficial because the tear tape 120 b is always in alignment with the area of structural weakness 12 .
- tear tape 120 is applied to both the inside surfaces 36 a and 35 a and the outside surfaces 36 and 35 of the bag 100 .
- the tear tape 120 is applied to border both sides of the score line or weakening 132 . Since the tear tape 120 is located on both sides of the score line 132 and on the inside and outside surfaces of the bag 100 a very consistent controlled or guided will be achieved.
- Tear tape 120 is interchangeable with tear string 120 a . Accordingly, a tear string 120 a could be substituted for the tear tape 120 . See, e.g., FIGS. 38 and 39.
- the tear tape 120 or the tear string 120 a used is made from a material, e.g., Thermoplastic material, that is compatible with the film 10 and which may be sealed, coupled, or bonded to the film 10 .
- the tear tape 120 or tear string 120 a may be formed of polyethylene or may be encased in polyethylene.
- a tear string such as tear string 120 a
- tear string 120 a may have various cross-sectional shapes, e.g., Round, square, triangular, etc., which may be used to enhance its ability to tear the parent film material 10 .
- the process by which the alternative embodiment having tear tape 120 is presently believed to be manufacturable is illustrated using an rpm 100 machine.
- the parent film 10 is fed over a predetermined number of rollers and toward the plow structure 200 .
- the parent film 10 after passing over dancer roller 203 a is die punched by die 210 to present parallel openings 121 . It is presently believed that the film 10 must pass over the dancer rollers 203 a so that they are kept sufficiently taught thus allowing openings 121 to be punched out accurately at predetermined positions, by die 210 , such that the positions of the openings 121 are always at the same or a uniform distance from each other.
- two rolls of tear tape 120 are feed over the parent film 10 and in parallel alignment with the parallel openings 121 such that the tear tape 120 preferably, but not necessarily, bisects each the parallel opening 121 .
- Tear string 120 a could be substituted for tear tape 120 . See, e.g., FIGS. 38 and 39.
- a header material 206 may be fed over the parent film 10 .
- the zipper or slider assembly 20 is also fed over the parent film 10 .
- the zipper assembly 20 Prior to being fed over the parent film 10 the zipper assembly 20 has a notch 22 a die punched, by die 214 and heat sealed by sealer 216 , at a predetermined position that is also designed to be in general alignment with the parallel openings 121 .
- the tear tape 120 Once the tear tape 120 is presented over the parent film 10 but before it is passed over the plow 200 it passes over a tear tape sealer mechanism 208 so that the tear tape 120 is sealed to the parent film 10 .
- the tear tape 120 could be tacked in place and subsequently sealed to the parent film 10 either before or after the plow 200 .
- the parallel openings 121 may be of any shape although circular is the shape that is presently preferred. Diamond shaped cuts could be used to further enhance initiation of the tear in the parent film 10 . See FIG. 37 .
- the notch 22 a as generally illustrated herein may be of an arcuate or radiused shape but the notch 22 a could also be made at a sharp angle such as a 90° angle. See FIG. 37 .
- the sharper angle is presently believed to add more stress to the structure of the zipper assembly 20 and therefore a radiused structure is presently considered to be preferred.
- the present invention should not be interpreted as being limited to solely a radiused notch 22 a as generally illustrated herein.
- the zipper skirts 16 are sealed to the respective sides of the parent film 10 at seal 14 .
- the header strip 206 if used, is sealed to the parent film 10 at seal 206 a .
- the side seal 30 a is made, which also seals the perimeter or edge 121 a of opening 121 . (note, if no tear tape 120 or tear string 120 a is used then it is presently considered best to add a tear notch 24 to the opening 121 to facilitate removal of the hood 11 .)
- An opening 123 is die punched in the package 100 to provide a point where the package 100 may be easily hung for display purposes.
- the package 100 is then cut along seam 101 from the V-fold portion of the form fill and seal machine and transferred to the fill and seal stations where fill opening 33 is opened and the package 100 is filled and gas is flushed through the fill opening 33 . Opening 33 is then hermetically sealed at seal 34 a.
- the zipper assembly 20 may be introduced subsequent to the plow structure 200 .
- the parent film 10 prior to being fed over the rollers 202 is still die punched by die 210 to present parallel openings 121 .
- the tear tape 120 or tear string 120 a may be feed over the parent film 10 and in parallel alignment with the parallel openings 121 subsequent to the plow 200 . See FIGS. 38 and 39.
- the tear tape 120 or tear string 120 a preferably, but not necessarily, bisects each parallel opening 121 .
- FIG. 38 and FIG. 39 the zipper assembly 20 may be introduced subsequent to the plow structure 200 .
- the parent film 10 prior to being fed over the rollers 202 is still die punched by die 210 to present parallel openings 121 .
- the tear tape 120 or tear string 120 a may be feed over the parent film 10 and in parallel alignment with the parallel openings 121 subsequent to the plow 200 . See FIGS. 38 and 39.
- the tear tape 120 or tear string 120 a preferably, but
- the openings 121 are provided, at a minimum, to facilitate access to the tear tape 120 or the tear string 120 a and to facilitate tearing and removal of the hood 11 to expose the zipper assembly 20 .
- the present invention may be used in combination with other VFFS and HFFS machines.
- the present invention could also be used with HFW machines.
- the method of the present invention is presently believed to require post-compression (commonly called post-squashing) of a predetermined portion of the track structures 20 b , with respect to the embodiment shown in FIG. 6 .
- post-squashing commonly called post-squashing
- the track mass 20 b may have a pre-compressed portion located with margin lob.
- HFW machines have a rotary jaw assembly, which includes a hinged side.
- the jaw assembly provides at least two advantages, either of which, separately or in combination, eliminates the need for pre-compression of the track mass 20 b .
- the jaw assembly provides a relatively long time, longer than the time provided by either VFFS or HFFS machines, for the application of heat and pressure sufficient to form the desired seal 30 a .
- the portion of the track mass 20 b that is targeted to be fused or sealed. (generally located within the boundary of margin 10 b ) is placed or fed into the jaw assembly so that it is placed toward and near the hinged portion of the jaw assembly and thus maximum mechanical advantage and force may be applied to the predetermined portion of the track mass 20 b.
- the track mass 20 b may be pre-punched with a die at the predetermined location 22 a (where the seal 30 a is also to be applied or created) prior to insertion into the fold 11 of the parent film 10 . Since the pre-punched area or notch 22 a would be synchronized to be in registration with the portion of the folded parent film 10 that is to be sealed, less energy (time, temperature, and/or pressure), due to the reduced mass to be sealed is required to consistently obtain the type of seal 30 a desired. (note, pre-punching rather than pre-compression could also be used with HFFS or VFFS machines.)
